ABSTRACT
The density and refractive index were determined for four binary mixtures of 1,3,5-trimethyl-1,3,5- tris(3,3,3-trifluoropropyl) cyclotrisiloxane with octamethyl-cyclotetrasiloxane, hexamethyldisiloxane, 2,4,6,8-tetramethyl-cyclotetrasiloxane and 2,4,6,8-tetramethyl-2,4,6,8-tetraethenylcyclotetrasiloxane at different temperatures T = (308.15, 313.15, 318.15, 323.15 and 328.15) K and atmospheric pressure using a DMA4500/RXA170 combined system. The excess molar volume, partial excess volume at infinite dilution, isobaric coefficient of thermal expansion, excess refraction indices, Lorentz Lorenz molar refraction and the deviation in molar refraction have been calculated using this data. The results have been incorporated into the Redlich Kister equation and used to estimate the binary interaction parameters and standard deviation. The values of partial excess volume at infinite dilution and excess refraction indices for the four binary systems at different temperatures were calculated using the adjustable parameters of the Redlich Kister smoothing equation. The factors that affect these excess quantities are discussed.
